I have been looking into the IS ducts but I'm not sure that they snap into the existing tabs that the grille's snap into. Can anyone confirm? The 335is inserts are not a direct fit and will require some modification based on my research.

I don't get why people hate on "time attacks" so much some say they are played out? ...i much perfer the time attack look as opposed to the CSL-style look (which is OK but not aggressive enough for me - with a few exceptions)
